更新后问题

如果更新到0.45.0可能会报如下错误

Installing build/Build/Products/Debug-iphonesimulator/temp.app
An error was encountered processing the command (domain=NSPOSIXErrorDomain,code=2):
Failed to install the requested application
An application bundle was not found at the provided path.
Provide a valid path to the desired application bundle.
Print: Entry,":CFBundleIdentifier",Does Not Exist

这时候可能需要对版本进行回退,打开项目的package.json文件将依赖会退到0.44.3版本。

"react": "16.0.0-alpha.6","react-native": "0.44.3"

删除node-modules文件夹,然后执行npm install。回到0.44版本。
